Question

When beams of red, blue and green lights fell on the same spot, the colour of the light becomes -; 1) white; 2) violet; 3) red; 4) yellow

Answer 1

When lights of different colors shine on the same spot on a white surface, the light reflecting from that spot to your eyes is called an additive mixture because it is the sum of all the light. We can learn about human color perception by using colored lights to make additive color mixtures


hence the colour will be white

Answer 2

yellow is your answer.
